I've noticed a noise coming from the tranny now that it is cold here (~30 def F.) at startup on my 2002 WRX sedan manual. It seems to be a grumply, grinding sound and if i puch in the clutch, the sound goes away. Let it back out and it comes back. Ths could only exists for not more than a minute in the cold of the morning when i come out to the car and it has sat outside all night. Has anyone else noticed this and have any comments before i call up the old dealer?
